CSS Borders


CSS Border Properties

The CSS border properties allow you to specify the style, width, and color of an element's border.

I have borders on all sides.


I have a red bottom border.


I have rounded borders.


I have a blue left border.


CSS Border Style

The border-style property specifies what kind of border to display.

The following values are allowed:

  • dotted - Defines a dotted border
  • dashed - Defines a dashed border
  • solid - Defines a solid border
  • double - Defines a double border
  • groove - Defines a 3D grooved border. The effect depends on the border-color value
  • ridge - Defines a 3D ridged border. The effect depends on the border-color value
  • inset - Defines a 3D inset border. The effect depends on the border-color value
  • outset - Defines a 3D outset border. The effect depends on the border-color value
  • none - Defines no border
  • hidden - Defines a hidden border

The border-style property can have from one to four values (for the top border, right border, bottom border, and the left border).

Example

Demonstration of the different border styles:

p.dotted {border-style: dotted; }
p.dashed {border-style: dashed; }
p.solid {border-style: solid; }
p.double {border-style: double; }
p.groove {border-style: groove; }
p.ridge {border-style: ridge; }
p.inset {border-style: inset; }
p.outset {border-style: outset; }
p.none {border-style: none; }
p.hidden {border-style: hidden; }
p.mix {border-style: dotted dashed solid double; }

Result:

A dotted border.

A dashed border.

A solid border.

A double border.

A groove border. The effect depends on the border-color value.

A ridge border. The effect depends on the border-color value.

An inset border. The effect depends on the border-color value.

An outset border. The effect depends on the border-color value.

No border.

A hidden border.

A mixed border.

Note: None of the OTHER CSS border properties (which you will learn more about in the next chapters) will have ANY effect unless the border-style property is set!
